To all whom it may) o oncera:

Be it known thatI, Gnome CQCL ARK, a

citizen of the UnitedStates, residing atDetroit, countyof Wayne, Stateof Michigan, have invented a certain new and useful; Inn provement inSwinging Stops for Slidable Hinged Sashes,,and declare the following tobe a full, clear, and exact description of the same, such as will enableothers skilled in the art to which it pertains to make and use the same,reference being .had to the acof this specification. y 1 1 I 1 s Theobject of this invention is: to provide a hinge stop that can be swungaway from the window, so as to allow the sash to-be swung inward forventilating the, room, or for cleaning the glass. Another object is toprovide a stop that can be either fastened or hinged at bothends toswing in a vertical or a horizontal plane and is for use in connectionwitha sliding. hinged sash. These and other objects and the severalnovel features of .theinvention in its preferred form are hereinaftermore fully described and claimed and shown in the accompanying drawingsin which, r Figure l is a cross section through a window, showing thestop; and the window in companying drawings, whichforin apart dottedlines, when swung inward to ventilate the roomQw Fig. 2 is a perspectivedetail of the hinge member at the bottomof the stop.

, The hinge fi is fastened to the plate :6, C H

which in turn is fastened to the hinge 7, winch connects both the plates6 ands. This hinge member is mounted directly on'the base plate 9, shownmoreparticularly 3, which is screwed to the window frame, being:provided with screw slots 10, which allow for adjustment thereof.Thescrew l1 passes through the washer l2v through the plate 8, andthrough the hole 13 in the plate 9.

This forms a. pivot, the plate 9 being solid with the window frame, andplate 8 being adapted to swing on the screw 11, as its axis. At the topof the stop is provided the two piecesl l; and 15, which are mounted soas r 4 to slideione below the other. Thestop in its normal positionbrings thetwo parts together, as shown in Fig. 4, and the thumbscrew 30in the part 1.4 can be turned up to bind the two parts 14 and 15together. The part 15 is slotted at its forward end at $81,

and is formed with theup-turned edge 16 on each side of the slot behindwhich the thumb-screw engages, thus preventing accidentaldisplacement ofthe stop by the window bumping it and forcing it out of place.

As can be readily seen from the drawing, by loosening the thumb screw3Qso that it can be moved over the projection 16 and out of tion of thearrow in Fig. orfit can be swung across the face ofthe window until theslot 31, the stop can be turned at right angles to the window frame, inthe direcbe swung on the screw 11 and the thumbscrew .30 asits hinges.In order 110.? swing the stop on the vertical pivots the catch 22 andcompanion member 21 should not be used.- The stop shownin-the-drawingsis of I a type for use .in a thick wall, and the dis tance from the sashto the innenedg'e {of thewindow frameis too reat to permit of the use ofa stop of that W'ldlihl In this type of window, one oftht, "best. ways0t remov ing the stop to-allow the window to swing, is

, to hinge tl est op as in this case, so it can window frame and laiddown upon the sill thereof, toal low a clear space inwhich the windowcan swing. I have shown in the drawing a method of pivoting this'stop onthe upper end on the thumb-screw 30, and at 'the lower end on the screwl1,so that it can be swung in a' horizontal plane. This arran'gementisintended forwindows having a narrow space between the edge of the sashga nd"th'e inneredge of" the window so that {when swung on the pivots1'1 and 30 as its yertical axis, it"can be folded back outside {ofthe'window frame and thus allow a clear spaceinwhich'the window can beswung. When'the stopsare outof the way, being understoodfthat there isa.stop' atieach side otti ei window, the window canbe swung inwardly,"the direction for; swinging the window being sliown in dotted lines inFig. 1. it is'inecessary to remove, the upper sash it can be slid toitslowermost position, at which point the parting strip 17 between thetwo windows can be removed, there being a parting strip 17 at both sidesof thewindow frame, and thus the sash ,2 can be swung to the sameposition as. the lower sash, it also being pivoted at its lower end tothe sash-cordf This parting strip 17 has a pin 18 attheupper endthereof, and a pin 19 at the lower end thereof, whichfit in sockets intlie'window frame. The lower cross bar of the upper frame projectsoutward over the parting strip 17 in its normal position, and preventsremoval there 0f. When the projecting cross barof the fwindow framepasses low enough to cover the solidvpart 20 of the parting. strip, the'pin 18 can be removed from its socket in' the window frame by swingingthe stop 17 outward across the window frame and then lifting it up todisengage the pin 19 from "socket. The window sash then can be swunginwardly as there are no projections on whichit would catch. In caseswhere the window sashes are very long, it can be seen that the hii'ig'edstop must also be very long and is liable to warp. To prevent this, aplate 2l, is fastened to the window frame, the window frame being cutout directly below it to provide aspace for the hooked end 22 of the,plate'23, which is fastened to the stop 4', this catch holding the stopand'binding it in position parallelwith window frame 1 and preventing itfrom warping. One ofthe novel features" of this inventio'nisje nbodiedinthe hinged joint, Fig. "2, which allows the "stop to be swung across"the" face of the window frame, or at a right "angle to it, or it can beswung in a horizon- Copis of this patent may be obtained for five centseach, by addressing the Commissioner of Patents,

tal plane on the point 11 and the thumb screw 30. Another novel featureis that the window can be swung inwardly, enabling the operator to cleanthe outside face of the glass, thus eliminating the troublesome anddangerous belts or ladders, which are commonly used for this purpose,and prevents the danger or anyone falling from the window from thenecessity of climbing outside to clean it.

From the foregoing description, it becomes evident that the device iscomparatively simple, affords a splendid means of ventilation, and isvery simple, ei'licient and convenient in operation.

Having thus briefly described my invention,rits utility and mode ofoperation, what I claim and'desire to secure by Letters Patent of the U.S., is

'1. In a window frame, a sash, a: stop provided to form a surfaceagainst which the sash bears, saidstop being provided with a hingedjoint adapted to allow movement of the sash in a vertical plane at rightangles with the window, and in a vertical plane parallel with the windowframe, and means for pivoting the stop to swing in a horizontal plane.

2; In a window frame, a vertically disposed stop provided with a hingedjoint at the bottom thereof, said hinged joint being pivoted to thewindow frame on a vertical axis and adapted to swing in a horizontalplane, said hinged joint being also tical axis'and adapted to swing in ahorizontal plane, said hinged oint being also provided with hingesadapted to allow the stop to be swung at a right angle to either of thehinges and a plate mounted directly beneath the hinged joint andfastened to the window frame and'providing, a bearing for the pivot towhich the hinged joint is fastened, and at the upper end of the stop afastening plate solidly mounted thereon, 'car rying a thumb-screwadapted to engage in .a longitudinally disposed slot in a similar platemounted on the window frame in such manner as to allow movement of theplates one below the other.-

In testimony whereof, I sign this specifi- GEORGE C. CLARK.
